Metal classification all metals may be classified as ferrous or nonferrous. Particular emphasis is placed on their commercial importance. Stokesley metals limited have a full set of licenses to work in the scrap metal recycling industry. Iron fe is the principal element of ferrous metals. Their main advantage over ferrous materials is their malleability. This can be a disadvantage since it excludes this metal from any application where magnetism is necessary or is an advantage. Ferrous and nonferrous metals are two different types of metals. The term ferrous comes from the latin word ferrum, meaning containing iron. Ferrous metals include all forms of iron and ironbase alloys, with small percentages of carbon steel, for example, andor other elements added to achieve desirable properties. They are generally more expensive than ferrous metals nonferrous metals are used because of desirable properties such as low weight e. Nonferrous metals are those which do not contain iron and are not magnetic.
In case the metal contains iron, it is known as a ferrous metal, otherwise a nonferrous metal. Ferrous metals have many important uses chances are youve seen a ferrous metal today. An alloy is a mixture of two or more metallic elements, which retains its metallic bonding character. A form of iron, steel is one of the ferrous metals that contain less carbon than cast iron, but considerably more than wrought iron. Ferrous metals are those which contain iron as their main constituent or base metal. Again, we are going to provide some information on each metal and its properties. It usually represents less than 1 per cent by weight of the typical municipal solid waste stream. Base metals the recovery of lead, zinc, copper, and nickel. The metals other than iron and alloys that do not contain an appreciable amount of ferrous iron are known as nonferrous metals.
Basic carbon steels are alloyed with other elements, such as chromium and nickel, to increase certain physical properties of the metal. Since nonferrous metals dont contain iron, theyre usually more corrosionresistant than ferrous metals. Examples include bronze copper and tin and brass copper and zinc, as well as num. For more specific information on metal and heattreating techniques, refer to tm 430106. They also have no iron content, giving them a higher resistance to rust and corrosion, and making them ideal for gutters, liquid pipes.
Nonferrous metals also include brass, gold, nickel, silver, tin, lead, and zinc. Ferrous and nonferrous metals chemical composition and. One of the most fundamental yet critical areas of metallurgy relates to the extracting of metals from ores, concentrates, scrap and other sources with a view to refining to the liquid state. Examples of non ferrous metals important nonferrous metals include aluminium, copper, lead. They are also usually more resistant to corrosion than ferrous metals. The chemical composition and properties of the ferrous and nonferrous metals.
Do nonmetals also have physical properties similar to that of metals. Ferrous word has been derived from the latin word ferrum which means contains iron. Sap sintered al powders, metal matrix composites with sic, al 2o3, etc. Aluminum aluminum ore is found as a hydrated aluminum oxide, called bauxite.
